8-Port ANH LED Descriptions

LEDs on the ANH front and back panels provide information about how the ANH

is operating.

Front-Panel LEDs

Figure 4-2 illustrates the three sets of status LEDs on the 8-port ANH front panel.

Table 4-3 describes the function of each of these ANH front-panel LEDs.

Loop Lights when the T1 interface is placed in loopback mode.

Sync Lights when the T1 port is synchronized with the T1 network.

Token Ring Interface (MAU)

RCVR (Receiver) Lights when the AN receives data from the network.

NSRT (Insert) Lights when you insert the AN into the token ring network.

WFAIL

(Wire Failure)

Lights when the token ring hardware detects a wire failure

condition.

Note:

All front-panel LEDs light briefly when you turn on the ANH; this

indicates that the ANH is receiving power.
